Specixication forming part of Letters Patent No. @ASML dated May '27, 1851.

T0 @ZZ whom/ it may concern.: y Beit known that LPARIs MARION WALKER,

of Marshall, in SalineI county, and State :of l

Missouri, have invented a new and useful'Machine for Breaking Hemp, called NlValkersv Hemp-Brake 5 and 4I do hereby declare thev following is a full, clear, and exact description of the same, reference beinghad to the annexed drawings, making apart of this speci oation, in'which* A Plate 1 is a perspectiv 1 Fig-.l 2, Plate 2, is a transverse section from thecenter. Fig. 4, Plate 2, is' a longitudinal elevation; and Fig. 5, Plate 2, is a groundeleval tion without the'walking beamand pitmen. Y

The

. breaking part of the machine `is composedof slats five inches wide, one and ,a 4half inch thick, reduced on the upper edge to half an inch,and then rounded. Nine ofthese, j Plate 2, Figs. 2, 3, 4, and 5, form the lower part, and are seven and a half feet long,resting upon independent upright supports. rllhey are let into those marked l, Fig. 2, Plate 2, -andsecured by mortise and tenon on the top of those marked l, Plate 2, Fig. 3, and` are ten inches from center to center in Fig. 2, Plate 2, and. six inches in Fig. 3, Plate 2.

-o', vPlate 2Figs. 2, 3, 4, and 5,'which side pieces are two inches by twelve in the center, .and six inches at the endsfand -is worked on the pin zt', Plate 2, Fig. 4. u The whole in its form and working resembles the common hande-view.- Figures ll,- -and 3, Plate 2, are end-sections.

brake, except that the number of slats is. increased, so that the whole length ofthe hemp is brought under the action of the brake at once.

:When shut down, ,the slats close in upon-each other four inches at the narrow end, While the cross-timber m,-Plate 2, Fig. 2,'is framed in'` loneinch higher'than m, Plate 2, Fig. 3, and the y'supports Z, Platev2, Fig. 2, areone inch' lower' 'than thosel marked i, Plate '2, Fig. 3,

and a reduction of the slats atthat point brings `the-,edges ofthe upper and lowerv onesto a level. The upper part ofgthe brake is con-` nected by the pitma'n s, 4Plate'2', Fig. 4, to the walkingfbeam e, Plate 2. Fig. 4; which walkf ing-beam is-,again connected bythe pitmaud,

The feeder' is formed of eight slats, u, Plate 2, Figs. 2, 3, l '4, and 5, seven and ahalf feet. long,'one and "a quarter inchpwide,l and threequarters `of an inch thick, having iron pins w,P'late 2, Figs. 3 and 4, four inches long, on the upper edgev at intervals of four inches, and secured at the same angles and distances apart as the slats k, Plate 2, Fig. 5, bylmortises and tenons, upon smallupright pieces o, Plate 2, Figs. 2, 3,'and 4,six inches long, and one anda half inch square. tenons into the frame-work of the feeder p, Plate 2, Figs. 2, 3, 4, and5, which frame-work is made of four timbers, one and a half byv three inches`,is.six feet long, and the same width as the frame-work of the upper part of the brake to which it is attached, and is suspended perpendi'cular under it by the rods, q, Plate 2, Figs. 2, '3, and 4, at such distance that when the upper part of the brake is raised the slats of the feeder will beone inch above thc lower slats of the brake.

These are secured by mortises and 'The franiework ofthe nmehine is goed solid it lis delivered at the end of the machine ihoil ok, fonr inches thick, puty together as in the drawings, which nre on asczileof half an inch to the foot.

The inode of operating the inaehine is thus: An attendant standing upon the frame-Work at u, Plate 2,'Pig'.- 5, receives lthe hemp sind' places 'it upon the lower lslantsj, Plate 2, Fig. f 5, et u, Platea2, Fig. 5. As the upper partis 4raised .by theziotion of the crank, the lfeedingslatsrise between the lower slats, lifting the hemp clear of the' lower slats, j, Plate 2, Figs.V 2, 3, 4, and 5, and Carrying it forward bythe motion communicated to it by the @am under the upper part of the brake. A t eveiy rise the hempii's carried forward six inches, until I onghly broke and nearly clean. A little beating and shaking finishes the article fit for market, the brake making from eighty to one hundred strokes per minute. 'Vhat I claim as my invention, and Wish io secure by Letters Patent, is-

The combining a slifiieient number oi' slats to breek the full length of the heni p :it once, in combination with the manner of-feeding, substantiellyias set forth.
